Acros Dying Not Sure What it Is

[EliMelly]

Hello,

So to preface I have a bunch of acros in the tank most are doing ok minus some unhappiness due to nutrient imbalances.

I have a colony that is out of nowhere dying and I’m not sure it’s an infection as I already lost a colony overnight to this when everything was perfectly stable.

I posted pics of the colony below and some of the other acros. Please advise!

What nutrient imbalances?
Stable and imbalanced is just as not good as unstable.
Can you post your readings please.

Yea so tank just got out of wack as I removed a ton of hair algae.

Nitrates: 0.1


Alkalinity: 9.9


Phosphates: 0.28

I added rowaphos to reduce phosphates and I’m going to start dosing ammonium bicarbonate to raise nitrates.

1) go slow to reduce po4. Take a week or more to lower to 0.2

2) go slow to raise no3. 0.1 is not terrible as long as fish are being well fed.

3) lower lights 10~20% for the next couple weeks and raise slowly.

4) don't add more alk. Let it lower to 7~8dkh

I'm not sure how to edit.
But, po4 you can keep lowering, I didn't mean to stop at 0.2, wanted to make that clear.

What about calcium? Make sure you are 400+

I manage calcium by water changes but I don’t test it

You should test it at least monthly.
No calcium = no growth

I’ll start testing monthly , it’s been quite a journey I had all my corals and tenuis taking off. Had an ich outbreak, removed fish, nutrients crashed, got horrible hair algae, only now removed the algae it was so bad, finally balancing parameters. I’m surprised I haven’t lost all my acros and Goni’s.

That’s how I do it. Dosing systems (AFR) keep it inline with alk, and water changes are even extra security on top of that.

The algae overgrowth could have been a major contributing factor to the coral issues.

That’s what I thought…
